1. Mass Hypnosis

Select an enemy unit within 18" of and visible to the psyker. Until the start of your next Psychic phase, the target cannot fire Overwatch, fights last in the Fight phase even if it charged, and must subtract 1 from its hit rolls. If the target has a rule that allows it to fight first in the Fight phase even if it did not charge, then instead of fighting last in the Fight phase, it fights as if it did not have that ability and did not charge.
